Keep on keeping on Garry!

Maybe you need to reduce the input power someway. You used 12.5 volts and 114 miliamps, Tom just used 6.1 volts and 81 milliamps in his last video.

And the magnetic flux... Couldn't you get a more powerful magnet, with stronger magnetic field?

Don't stop now!

I'd never heard of those before.

Yes Raps !

Tom has 3,200 feet of wire and less input, like you say, so i can't wait until he builds his rectifier.

I want it ALL and i want it NOW ;+}

3,200 feet?? Wow!!

I'm a complete moron about electronics... What are the factors that determine the amount of amps of the output of a generator? I read somewhere that the thicker the wire the more amps the wire will produce... Is just it?

Generators are easy. Moving copper wire through a magnetic field creates electricity, i find that amazing all by itself.

Noob question time again from me ...

So, Ohm's law, in relation to the function of a resistor, states :

V=IR.

What i don't understand is, in the modified bedini circuit i'm using to drive this motor, when i turn the 1K pot that's used to find the 'sweet spot', the current draw goes down, but the motor speed goes up ?

What blindingly obvious thing am i missing this time ?

Cheers Clever Fellas ;+}

Ok..you are talking about adjusting R3 in the magnetman's
circuit diagram above.

The R3 adjustment is a trade-off because of the 2n3055
transistor.  In a bipolar transistor the amplifier is
a current gain device, so base current is necessary, but
it also is wasted power flowing to ground through the emitter.
Just like before, your drive coil makes the rotor go and
the sense coil which is an output coil makes the rotor
slow down the more current that flows, The rotor is doing
work on the transistor base. R3 trades off so just enough
current flows out to make the transistor work but not so much
as to make the rotor slow down too much. So it is a sensitivity
adjustment. It is necessary because of the differing transistor
characteristics in the real world. See..Impedance matching
is the name of the game in the free energy field. You want
the energy to come out to you, not be converted to heat
internally by inefficient couplings ect.

Hi All,

I just bought a "2 inch" diameter/1/2 inch thick Diametric magnet that will fit inside my flux coil setup easily.  I hope to have it within a week. It has a gauss rating over 13,200 !!

If this bad boy does not produce some type of overunity results I will throw in the towel.  I already have the plastic side plates with carbon fiber axles made to bond to the magnet.  It is a DISK Diametric magnet - not a ring with a hole through the center.  Will post results.

I will figure out both AC and rectified DC Power.

I tidied up the circuit by improving the contacts and mounting in a project box, my first one it's great fun !

Also changed height of coil, it wasn't dead-centre vertically before.

Also using 100k resistor rather than pot as a load.


System components :

Drive circuit: Bedini, no JonnyDavro relay. Using 10k, 3-contact linear pot.
Drive coil : Bifilar, single coil.
               Trigger wire : 0.25mm.
               Induction wire : 0.28mm.
Magnet : Neo @ 6,100 gauss.
Full wave bridge rectifier, shop-bought, maximum reverse-current is 10A per diode.

Load resistor : 100k

Resistance of Bedini pot : ~1200

Peak performance result :

Input : 9.43 VDC @ 0.075 A = 0.70725 W
Output (rectified) : 41.5 VDC @ 0.035 A = 1.4525 W

Apparent COP = 2.053729232944503 ...

I ran the test 10 times and all results were similar, these are average figures.

*EDIT* What's an easy way of switching between the PSU and the rectified output ? Can i just connect the output to where the input goes to begin with or will that blow my house up lol ? *EDIT*

Try using a DPDT (double pole double throw) switch.  When you throw the dpdt, the psu turns off and the output becomes the input.  If it keeps running, time and film it.  Put the set up on a glass table, or or glass top of some type when filming.

Good Luck!

Cheers,

Bruce

Nice work there Deepcut.  If you want to really get a fast switchover on the input (from the output) I'd suggest a double pole double throw relay if you happen to have one around.  It would normally get it done faster than a switch (depending somewhat on the switch).  On the other hand if your motor tends to keep up the RPM fairly well for a couple seconds after being switched off then it may not make any difference using a relay over a regular DPDT switch.  Of course having a disconnect somewhere in the setup would be advised just in case it does starting going faster thus producing more power and looping into higher speed etc. to self destruct mode.   We can all hope you see that problem at least  ;D  so just have a way to unplug or turn off if you get lucky.
